Notes
Almost totally inert, COILTEF can be
used with all industrial solvents, chemicals, and
corrosive materials even at elevated temperatures. It
does, however, react with fluorine, molten sodium
hydroxide, and molten alkali metals.
Fluoropolymer's non-stick property allows transport of viscous, sticky material without line clogging. It also offers outstanding aging resistance.
COILTEF is manufactured through a fabrication process which heat sets the coils. The coils should remain stable up to 200°F. At higher temperatures the coils will begin to relax and lose their set. If the application involves elevated temperatures, in-house testing is recommended.
COILTEF may be steam or chemically
sterilized in-line with any industrial cleaner, solvent,
or sterilizing method. Care should be taken with steam
sterilization of COILTEF to prevent coil relaxation.
Testing is recommended.
COILTEF can be manufactured from
.085" to 1/2" tubing ID. The coil diameter can
be produced from 3/4" OD to 4" OD.
PFA formula is available by special order only.
Other tubing materials can be used to create custom retractable coils. See our Custom Coiling page for more details.
